7.1 Introduction
The PPC-120/140 has an on-board PCI flat panel/VGA interface. The specifications and features are described as follows:
Chipset
The PPC-120/140 uses a C&T 65555 chipset for its PCI/SVGA controller. It supports many popular LCD, EL, and gas plasma flat panel displays and conventional analog CRT monitors. The 65555 VGA BIOS supports monochrome LCD, EL, color TFT and STN LCD flat panel displays. In addition, it also supports interlaced and non-interlaced analog monitors (color and monochrome VGA) in high-resolution modes while maintaining complete IBM VGA compatibility. Digital monitors
(i.e. MDA, CGA, and EGA) are NOT supported. Multiple frequency (multisync) monitors are handled as if they were analog monitors.
Display memory
With on-board 2 MB display memory, the VGA controller can drive CRT displays or color panel displays with resolutions up to 1024 x 768 at 64 K colors. The display memory can be expanded to 4 MB for true-color resolution of 1024 x 768.
Display types
CRT and panel displays can be used simultaneously. The PPC-120/140 can be set in one of three configurations: on a CRT, on a flat panel display, or on both simultaneously. The system is initially set to simultaneous display mode. The CD-ROM disc includes three *.COM files in the subdirectory Utility\vga\ which can be used to configure the display. In order to use these configuration programs, type the file name and path at the DOS prompt.
CT.COM: Enables CRT display only
FP.COM: Enables panel display only
SM.COM: Enables both displays simultaneously
